DVD writer burning way to slow



[qanda]This thread is about the LG GSA-H55N. Click here to see full specs[/qanda]Recently i experienced that my dvd writer is not able to write the dvds. Formerly i used different brands of dvds. But finally i sticked to MOSERBAER DVD-R. I had already brought 30 dvds. But the problem is that when i used Nero 7 to write the dvd with some AVI files, i realised that it almost took some 35 minutes and shown me that to complete the time remaining is some hundreds of hours. I also noted that the speed at which the disc is writing is 5kbps. I dont know what to do. My LG dvd writer is a new one which i bought just 2 months back.
[ I had already verified that under the IDE ATA/ATAPI controllers the transfer mode is set to DMA]
Every suggestion is so valuable for me because iam a newbie.
